"If I can contribute to the offense, it's always nice, but I think that we are more proud of keeping our net clean from the pucks going in," said Chara, who gave the Bruins a 1-0 lead 13 minutes into the second period and added an empty-netter with 23 seconds left.

Fittingly, Halak got the only assist on Chara's second goal as he capped off his second shutout as a Bruin and 44th of his career.

"Every time you start a game or play a game, you're hoping to get a win," Halak said. "If you can get a shutout, that's always more special."

Brian Elliott kept Philadelphia close with 22 saves, but the punchless Flyers couldn't capitalize on the few chances they had to beat Halak. Philadelphia's frustration boiled over in the third period when the Flyers hurt their own chances to rally with six penalties.

"We have to push it in the right direction a little bit harder. That takes mental toughness right now because obviously we're going through a tough stretch here and this was a tough loss tonight," Philadelphia coach Dave Hakstol said.

Halak was in position the few times he was tested, stopping a one-timer by Claude Giroux from the right circle with about eight minutes left in the second period. The Bruins got it going the other way and took a 1-0 lead on Chara's slap shot from the blue line through traffic. It was the 197th goal of Chara's career and first since the second game of the season.
